Dear Experts, I am new to this forum and want your help to solve my problem. I am using ArcGIS 10 and my problem states as: I have a set of 46 monthly rainfall rasters 1. i want to extract the maximum and minimum pixel value from the the stack of 46 raster as MAX and MIN 2. Then using the equation shown in attached figure [ATTACH=CONFIG]25149[/ATTACH] I have to calculate the cumulative probability of each x 3. where x is each individual raster (total 46) 4. I have already calculated the values of "a" also in the form of a raster and would like the program to pick these values from that respective raster. 5. The summation equation should run from n=1 to n=Max repeatedly I would highly appreciate of a python expert who writes a few lines script for me to solve this
